Hey everyone newbe here, Im new to mustangs this is my first. I bought a 90 notch with 170k all original motor and tranny (runs great happy to say) which is impressive to me because I use to think Fords were ****ty and didnt last but I have big plans for the car, the time is coming to do some serious work I want to go all out 351w style, my buddy put a 427w in his 95 stang and he said it was pretty challanging but I guess for that year they dont make much to do that swap. I was researching on a Dart 351w 4 bolt main block and heard they are the stongest as they get. My real question is what all do I need to make the swap happen? are there any serious modifications to make it happen?[:o]
